Simple amp using tip142 147

Hi guys
I think its a good amplifier specially for amateur(meee [emoji846])
So i made 2 circuits of it and im trying to make one as a car amplifier[emoji51]
You can find the car amplifier by searching "190w rms darlington car amplifier"

This does not look like Class-D to me. Am I missing something?

[emoji848][emoji848] high power...low heat
thinking Maybe its a b class[emoji52]
Will you delete it[emoji853]

that schematic layout is making my brain hurt!

The design is essentially class B, and fairly conventional if i have managed to untangle the signal flow properly!

Anyway.. its powerful(at dual 49v and most volume my 3A fuses burned) so its easy to make and cheap

That's a lot of power for 1 pair of transistor. 2 pair would be better especially if you plan to run 4ohm loads. Greg
